' EXERCISING SWING.

Application led February 12,1926. Serial No. 87,776.

My present invention has for its object to provide an exercising swing, and to this end, it consists of the novel devicesl and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which' .illustrate the inventiom like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view principally in front elevation, with some parts sectioned on the line 1-1 of Fig. 2;

Fig. 2 is a view partly in side elevation and partly in Avertical section, taken on the line 2 2 of Fig. 1;

Fig. 3 is a fragmentary view partly in plan and partly in horizontal section; and

Fig. 4 is a detail view with some partssectioned on the line 4 4 of Fig. 1, on an enlarged scale. Y

The swing, as shown, is carried by a frame comprising a rectangular top member 5 supporte-d on laterally spaced pairs of legsl 6. The legs of each pair 6 are in converging relation and are rigidly connected at their tops by a tiebar 7. The swing has a seat 8 that rests on set-screwequipped collars 9 on a pairof suspending members 10carriedl by a rock shaft 11, the ends of which are journaled in the tiebars 7. The suspendingmembers 10 are in the form ofmetallic tubes arranged to turn on their longitudinal axes by having their upper end portions mounted in eyes in the i'ock shaft V11 and their lower end portions mounted in bores in the seat 8. Set-screwequipped collars 12 are applied to the upper ends of the suspending members 10, loosely rest on the rock shaft 11 and support said members therefrom.

A yoke-like foot rest 13 is attached to the suspending members 10 by having its arms inserted into the lower ends of said members, and which members are swivelled to said arms by set screws 14 having threaded engagement with said members and extending into circumferential channels in said arms.

The swinging members 10, above the seat 8, Aare provided with crank-actingV hand holds 16 having variable throw. Each suspending member 10 is formed from two tube sections, the inner end portions of which are bent laterally outward. The crank-acting hand holds 16 are in the form of Ushaped rods, the arms of which are inserted into the laterally bent inner ends of the suspending members 10 and adjustably secured thereto by set screws 17.

To setup swinging movement of the swing under the action of the turning move ment of the suspending members 10 by the crank-acting handholds 16, there are provided foreach suspending member pulling connections that are reversely extended vin the plane of the swinging movement of the swing. These pulling connections for the respective suspending member 10 include a crank arm 18 secured thereto, above the rock shaft 11, and a pair of cables 19 having one of their ends attached to the crank arms 18 and their other ends attached to a pair of connected ears 2O swivelled to said supporting member, the intermediate portions of said cables being arranged to run over anchors in the form of guide sheaves 21. The crank arms 18 project substantially diametrically opposite the cooperating crank-acting hand holds 16 and the pairs of ears are held between opposing set-screw-equipped collars` 23 on the suspending members 10. The guide sheaves 21 are journaled in forks on nut-equipped bolts 24 that eXtend through theY verticalmembers of the frame member 5. Coiled springs 25 are compressed. between the frame member 5 and nuts on the bolts. 24, and yieldingly hold the guide sheaves 21 to take up slack in the cables 19.

By adjusting the collars 9 on the suspending members 10, the seat8 may be raised or lowered in respect to the foot rest 13, and by radially adjusting the crank-acting hand holds 16 in respect to the suspending'meinber 10, the throw thereof will be varied, at wil It will be -n'oted that the crank arms 18, are provided with a multiplicity of longitudinally spaced holes in which the respective ends of the cables 19 may be secured to vary the throw of said crank arms. By raising or lowering the ears 20, by means of the collars 23, the leverage of the pulling connections on the suspending members 10 may be varied, at will. l

The operation. of the exercising swing may be briefiy described as follows:

The person wishing to take exercises sits on the seat 8 with his feet on the foot rest 13 and takes hold of the crank-acting hand holds 16. Then, by swinging said hand' holds to turn the suspending members -10 back and forth, the crank arms 18 are oscillated to produce the required pulling action to set up swinging movement of the swing.

The action obtained by the improved swing is substantially like the action obtained in rowing and is especially well adapted for developing the chest, back and arms.

What I claim is:

l. An exercising swing comprising an overhead rock shaft, a pair of carrier-suspending membersmounted on the rock shaft to turn on their longitudinal axes, and pulling connections including cranks attached to the suspending members, said suspending members having cranks by which they may be turned for operating the pulling connections'V to set up swinging movement of the swing 2. An exercising swing comprising an overhead rock shai't, a pair oi" carrier-suspending members mounted on the rock shaft to turn on their longitudinal axes, and res versely acting pulling connections attached to the suspending members, said suspending membershaving cranks by which they may be turned for operating the pulling connections to setup swinging movement o1 the swing.

3. Anr exercising .swing comprising an overhead rock; shait to a pair of seat-suspending members mounted on the rock shaft to` turn on their longitudinal az-res, and pulling connections inclu-ding cranks attached to the suspending members, said suspending members having crank-acting hand holds by'whic-lrthey maybe turnedi'or operating the 'pulling connections to set up swinging movement oi" the swing.

t. The structure defined in claim 3 in which the cranks in said connections have a variable throw.

5. The structure defined in claim 3 in which the crank-acting hand holds have' a variable throw. y

6. .AnV exercising swing comprising an overhead rock shaft, a pair of seat-suspending members mounted on the rock shaiit to turn on their longitudinal axes, and reversely acting pulling connections including cranks attached to the suspending members, cables. having one of their endsl attached to the suspending members' and their other ends attached to saidcranks, and anchors over which the intermediate portions of the cables are arranged to run, said suspending members having crank-acting hand holds by which they may bev turned for operating the pulling connections to set up swinging movement or the swing.

7. The structure defined in claim 6 in which the ends of the cables attached to the suspending members may be raised or lowered.

8; The structure defined in claim 6, in which the anchors are yieldingly held.

9. rl"he structure dened in claim 3 in further combination with a foot rest secured to the suspending members by swivel connections.

10.An exercising swing comprising an overheadfrock sha't, suspending members carried by said shaft, a seat carried by the suspending members, said members being free to turn on their longitudinal axes in respect to said shaft and seat, and pulling connections including cranks on the suspending members, swivelled ears adjustably attached to the suspending members, anchors, and cables having one of their ends attached to said cranks and their other ends attached to sai-d ears, with their intermediate portions arranged to run over said anchors, said suspending members having crank-acting hand holds by which they may be turned for operating the pulling connections toV set up swingingv movement of the swing.

In testimony whereotl aiiix my signature.
